To be honest I thought his response was refreshingly untypical. Normally any player will just faff on about how Madrid are a top, top side and they'e done themselves proud and it shows what level the club is at etc. Nice to see a footballer being so genuine about their disappointment. It was odd hearing a footballer talking that way about their team throwing away the win but I'd rather we hear more like that. I can see Mancini's problem there though as normally the manager will frame the context of the loss not the player. Doesn't make either right or wrong but hard of Mancini to try and spin any positives out of it when Hart comes out and says there are no positives they just threw it away.
Mancini does come across as incredibly childish at times. Hart's response is a fairly typical one to a defeat in that manner. What else was he supposed to say?
